Beschreibung
Orsat suction and pressure bulb is a rubber laboratory accessory designed for controlled aspiration and delivery in gas analysis and liquid-handling tasks. Made from rubber, the bulb provides both suction and pressure functions required by classic Orsat apparatus as well as general pipetting. With a net weight of 0,072 kg, the compact form from manufacturer Witeg allows convenient one-handed operation. It belongs to the group of peeleus balls, suction bulbs and pipette safety aids that eliminate the need for mouth pipetting. Laboratories use the Orsat suction and pressure bulb for safe reagent transfer, titration support and volumetric work with glass or plastic pipettes. The elastic rubber construction withstands repeated compression and release cycles typical of routine analytical procedures. Suitable as a macro pipetting aid, it delivers reliable volume control when fitted to standard laboratory pipettes. Research, teaching and quality-control environments value this durable accessory for improving operator safety during everyday liquid handling. Supplied as 1 pc, the bulb connects readily to Orsat gas-analysis equipment and conventional pipettes. Its dual suction-pressure capability makes it a versatile tool across multiple analytical and preparative applications.

Questions about Orsat rubber bulb
What is this article?
Orsat rubber bulb is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Pipette stands, calibration & accessories, inside Liquid handling, in Präzisionsinstrumente.
A pipette stand holds piston pipettes upright so liquid does not run into the piston. Calibration accessories and certificates are how a pipette's delivered volume is shown to be inside tolerance. A stand is also a carousel. The certificate belongs to one pipette, identified by serial number.
A piston pipette delivers a set volume of liquid by air displacement or, for viscous and volatile liquids, by positive displacement. A single channel is the ordinary tool. A multichannel repeats the same volume across a row of a plate. A bottle-top dispenser meters reagent from the bottle it sits on. The accuracy is a property of the pipette and of how it is used, which is why calibration and a certificate exist. Piston-operated apparatus is treated under ISO laboratory apparatus. The volume unit sits with the BIPM and NIST.
